axle. It is plain therefore that the link must be of such length as to permit ofthe required movement of the door withoutthe movement of the wheels being restricted by the pendents. In addition to spacingthe wheels the link keeps the axles parallel and prevents displacement of the wheels-should they Jencounter an obstruction, such as a roughfpla'ce in the track.

The freedom of the axles in the wheels permits the latter to -move lai-terally'with r'eference to each other and thus find the lowest point in the troughs of fthe track, and their treads being formed on asmaller radius 'than that ofthe troughs, insures perfect freedom from 'rubbingl frictionlbetween the wheels and track. lThis feature is principally useful vwhere the hanger is ,newly .-ihstallech'as with the first -few movements-of thfdoor -to and fro the wheels -find their places andthereafter the axles and wheels are vlikelyft-o operate 'much as though they were integral. But this initial self adjustment is a valuable function and contributes very materially to the remarkable freedom of movement and noiselessness that characterizes this hanger; the hubs of the wheels are made -conical to prevent rubbing against the sides of ,the rider. lith these provisions, and thel perfect rolling action between the rider Aandil axles-cylinders rolling against a plane,-' it is clear that there is no rubbing friction between the parts referred to. yThe link may be made. of any one of a variety of-substances, but I prefer hard wood thoroughly impregnated with a substance which will render it impervious to moisture and act toA some extent as a lubricant. Parafiin has'ibe'en found satisfactory for thispurpose. Because of its slight weight the'fricti'on between the link and axles is insignificant. An'iniportant factor in the reduction of'friction at these points is` the fact'that the rolling `action taking pla ce. between the,rid'erandaxles gives to the latter `af hard, lbright surface.

` The'rider shown in Fig. '5 is 'composed'. of two dat strips of steel with the -penolentsQQ riveted between'them, while the one shown in Fig.` 6 is a solid square bar. When this form is used slots have. to be milled inthe ends to receive the .pendents The two-.part rider is satisfactory A'for any but veryh'eavy or wide doors. Another feature which*l contributes very much to* the success Vof this type of hanger is thehiannerbf attaching it to t-he door. The lo'ops 30` are vcapable of turning on the angle'bolt so as to allovvthe rider to rest squarely o'n'zthe axles. This prevents a tendency whi'chthe ri-d'er'might have to run tol 'one side andv h'ugthe wheel hubs if the 'rider were tilted 'more or less, which itmight .be if' "securedf tothe door sidlyl The 'structure illustrated in Figs. "9 to v12 -rinclusive embodies the "principles A'already The threads of the bolts may be slightly ment of the hanger.

described in a different form. A single track 50 is secured to the wall by any well known means., and grooved wheels 5l, having axles 52, carry a rider composed of parallel strips 584-53, one strip resting on each of the axles. The strips are united by screwsI .54 vpassing through spreaders 55, andv also by the upper ends of the pendents 56 which,

being-formed into a U shape-are riveted to the strips. The lower ends vof the pendents are bent inwardly and f' provided-with open v lslots y57 to receive the bodies of bolts 58. A recess-59 is formed in each pendent of such size as to allow the head'of the bolt tof pass through, thereby enablingthe door toI be attached after the hanger is i-n place and the bolts screwed into or otherwise atta'chedto the door. The recess extends a short distance on the horizontal part' of' the pendent, as-v'fill'be seeny infFig. 16. Clip 6() having upturned ange'sG-and va slot which reaches `Afrom one flange to 'the vother (not shown) is 'strung lon each bolt above the jambf-nut 63, and after the bolts are inplace in the slots 57 the clips are pushed `up intoplace, the flanges 62 serving to close the ends of slots 57. After the nuts 63 are screwed up against the clips, or even lnear them, itI is impossible for the bolts to lslip out of the pendent slots;

mutilated after the nuts are screwed up, to prevent the nuts working far eno-ugh 'down to let thev bolts out.

4In this hanger the link is composed of two v strips 65 fastened together by screws and spreaders 66. The apertures 67 are'formed so -as to afford support for the link, as be`` fore described, but if desired, however", the stirrups before describedinay be used for' supporting lit. The links engage the part of the axles which is engaged by the rider' as in the type ofhanger first des cribed,'which not only economizes. space but reduces kfriction as hasv been explained. The flanges of thewheels are made to flare, and the'hubs are conical, both to eliminate rubbing against thefv sides fof themembers they come in contact with. The treads of the wheels fare crowned-so as to insurea balanced stra-in on' the hanger. The screws which ent-er spreaders 66 may if 'desired kbe loose in the links soas to allow th-e links to adjust themselves to conditions.

It will be noticed that theA axles are per-A mitted to run almost to the ends of the rider, but the'a'xle of onewheel is preventedfrom goingbeyon'd'the end by the other wheel colliding with the spreader 55. In this way `the wheel base of the hanger may be yvery long in proportion to the widthof theldoor.

:The heads of the bolts being quite closet'o the lower-edge of the track prevents `'derail- It .is not 'to beunderstood that either emf each has advantages which commend its use under certain circumstances. Either type l,is susceptible to modification f without de? parting from the substance or exceeding the axles, a link mounted on the axles for the purpose of connecting the wheels together, the apertures for the axles being bored so near lthe yupper edge of the link that lateral slots areformed which expose narrow portions of Athe axles but enclose enough thereof to support the link, and a rider resting on said exposed portions. 5

In a door hanger, a track having a double tread, wheels to roll thereon, said wheels being arranged in pairs, one wheel rolling on each tread, and connected by an axle, a link mounted on the axles soas to connect the pairs of wheels together, the apertures for the `axles being bored so close to the upper edge of the link that lateral slots are formed which expose narrow portions of the axles but enclose enough thereof to' support the link, and a rider resting on said exposed y portions of the axles. f

3. Inl a door hanger, a track having a double tread, wheels to roll thereon, said wheels being arranged in pairs with one wheel resting on each tread; each'wheel being bored axially, axles comprising end portions which fit freely in the wheel bores, and an enlarged central portion, the steps at, the points where the diameters change forming shoulders which prevent. the axles slipping an excessive distance in either direction but permitting suicient endwise movement to allo-w the axles and wheels to accommodate themselves to conditions, a link mounted on said central parts of the axles to connect the pairs of wheels together, the apertures or the axles being bored so close to the upper edge of the link that lateral slots are formed which ex pose4 narrow portions of the axlesl but enclose enough thereof to support the link, and a rider resting on said exposed portions of the axles.

4. In a door hanger, a track, wheels arranged to roll thereon, said wheels having axles, a link whereby., said 'wheels are cou@- pled together, said link having recesses in its upper edge in which the axles lie and rotate as the wheels rollA along the track, said recesses being open at the top so asto` expose the vupper parts of the axles; a rider resting on said exposedparts of the axles, means *1 i for attaching the riderto a door, and means for supporting the link.-
